This diacetylenic complex as well as the perfluorinated organic compounds 2,3,5,6-tetrakis(pentafluorophenyl)-1,4-benzoquinone, 2,3,4,5-tetrakis(pentafluorophenyl)cyclopentadienone and 2,3,4,5,6,7-hexakis(pentafluorophenyl)cycloheptatrienone are also obtained from thermal reactions of (η5-C5H5)V(CO)4 and bis(pentafluorophenyl)acetylene in solution. Photolysis of (η5-C5H5)V(CO)(C6F5CCC6F5)2 in the presence
(η的光解5 -C 5 H ^ 5)V(CO)4在二一个或二当量(五氟苯基)乙炔产率(η的存在5 -C 5 H ^ 5)V(CO)2(C 6 ˚F 5 CCC 6 ˚F 5)。在此加合物乙炔一个一氧化碳配位体可通过三苯基膦光化学移位以产率(η 5 -C 5 H ^ 5)V(CO)[P(C 6 H ^ 5)3 ](C 6 ˚F 5 CCC 6 ˚F5)。该复合物也由(η的光解得到5 -C 5 H ^ 5)V(CO)3 P(C 6 H ^ 5)3在二的存在(五氟苯基)乙炔。在真空中,熔融相(η的热分解5 -C 5 H ^ 5)V(CO)2(C 6 ˚F 5 CCC 6 ˚F 5)和双(五氟苯基)乙炔产生(η 5 -C 5 H ^ 5) V(CO)(C 6 ˚F 5 CCC 6 ˚F 5)2。该二炔复合物以及全氟有机化合物2,3,5,6-四(五氟苯基)-1,4-苯醌,2,3,4,5-四(五氟苯基)环戊二烯酮和2
